Q6008RH4

Triacs Overview

The Littelfuse Q6008RH4 is a standard triac designed for high-reliability applications, rated at 600 V repetitive off-state voltage and 8 A RMS on-state current. It operates within a junction temperature range of -40 °C to +125 °C and utilizes a TO-220AB package with three pins. Key electrical characteristics include a maximum DC gate trigger current of 35 mA, a maximum gate trigger voltage of 1.5 V, and a maximum holding current of 35 mA. The device exhibits a maximum leakage current of 0.01 mA and features a critical rate of rise of off-state voltage of 425 V/µs.

Triacs Feature Summary

• High reliability construction suitable for mission-critical environments
• Direct connection capability via isolated tab mounting configuration
• Robust thermal performance supporting operation up to 125 °C

Triacs Applications

• Industrial motor control systems
• Solid-state relay implementations
• General-purpose AC power switching circuits

Triacs Procurement Notes

Verify the specific suffix designation against official Littelfuse documentation to confirm exact pinout and isolation requirements. Confirm RoHS compliance status through the manufacturer's current datasheet revision. Ensure the TO-220AB package dimensions match the target PCB footprint before finalizing procurement orders.

Triacs Selection Notes

Select this component when an 8 A RMS current rating and 600 V blocking voltage are required in a through-hole format. The TO-220AB package facilitates effective heat dissipation for moderate power loads. Verify that the 35 mA gate trigger current aligns with the driving circuit capabilities.

Triacs Part Context

This part belongs to the Littelfuse Q6008 series of standard triacs. The series provides robust solutions for AC power control applications requiring reliable switching performance. The Q6008RH4 variant specifically denotes the through-hole TO-220AB packaging option within this product family.

Triacs Replacement Considerations

Cross-reference with other manufacturers offering equivalent 600 V, 8 A triacs in TO-220 packages. Verify pin compatibility and thermal resistance values before substitution.
